Largest construction vessel of the world enters the Black Sea to work on TurkStream

31 May 2017

Pioneering Spirit has entered the Black Sea today in order to commence pipelaying towards the materialization of the TurkStream Offshore Gas Pipeline project. Pioneering Spirit is a specially designed construction vessel from the fleet of Swiss maritime company Allseas. At a length of 382 meters and a width of 124 meters, Pioneering Spirit is the largest vessel in the world, designed for deepwater pipelaying as well as the installation and removal of large oil and gas platforms.

After arriving in Anapa, Pioneering Spirit will start with preparatory work before deep water pipelaying. Audacia, another vessel belonging to Allseas, has already started pipelaying in the Russian coast earlier in May.

Background

The TurkStream Offshore Gas Pipeline will consist of two parallel gas pipelines stretching for 930 kilometres across the Black Sea, each with a diameter of 81 centimetres and an annual throughput capacity of 15.75 billion cubic meters. TurkStream will be the first pipeline of its size to be installed at a water depth of up to 2,200 metres. One of the pipelines will cater for the Turkish market, while the other will stretch to the Turkish-Greek border to ensure reliable deliveries of Russian gas to the European markets. In line with the schedule, first gas is expected to flow through TurkStream by late 2019.
